I have many lipomas around my low rib cage. My problem is that after sleeping 4 to 5 hours I am having muscle spasms in my back and sides. I also have one located lower in my back near my spine on the left side. I feel like they are in my muscle tissue because after I get up and moving around my pain subsides. I have seen a Dr for these but he said he couldn t feel them. I can feel them and was wondering if you can find them with ultra sound. I work full time and am exhausted by the end of the day from not sleeping well. Looking for a doctor willing to take another look and help relieve my pain. I know they are nothing to worry about but these are painful when they have pressure on them.
